invented new and useful improvements in Lubricating Apparatus Of'WillCllthe "1- lo'wing is a specification My invention relates to apparatus forlubricating the guide rails of elevating machiner or the like andparticularly to that type supplying lubricating fluid, at prccleterminedpoints in the elevator travel, to suitable lubricant distributers of*lubricw tors which are located on the elevator carriage and bearagainst the exposed faces of the guides to be lubricated.

One object of the invention is to produce an ,appzrjistus oi theaforesaid type which adapts i self to the elevator side play in. such amanner as to furnish at each actuation of the apparatus a substantiallyuniform quantity of lubricant to the lubricators, thereby eliminatingthe disadvantageous feature in known apparatus of this type of supplyinga continuously varying quantity of tiuicl more or less dependent uponthe lateral t isplacement of the elevator with respect to the guides.

The invention further contemplates an apparatus whoseparts may bereadily adjusted to supply the exact amount of lubricating fluidrequisite for the particular elevator; whose parts are so constructedand arranged with relation to each other as to reduce to a minimumsudden jars and pounding lue to the operation of the apparatus; andfurther a lubricating appa futus characterized by its rigidityin'construction, by its simplicity in operation and parts, and by itsreliability for service with a miniiriuiu of attention.

In addition to the above desirable features other advantages of myapparatus will pear lz-y reference to the following described drawingswhich are merely illustrative of one 1" rm of my invention, wherein:

This reservoircarries suitable luil'lCilE'iij distributors or lubr cators 3, similarto the distributers shown and illustrated in my former Patent No.821,072., issued May 22, 1906, these distributers being suitably firedto the reservoir as by uprights 4e bolted to suitable lugs 5 on thebottom of the res ervoir 1 (Fig. 6). It is to he understood that alubricant is supplied to theexposed faces of an levator guide rail (notshown) throw, ese distributers 3 and a collecting 5 cone 6, preferablyincased in a Z? of glass, is provided with ducts lea lg to and supplyingthe various distrihuters 3, all in a similar manner to e disclosure inabove mentioned goutent. go

slotted to straddle the disk 10. The disk is carried by a shaft suitablyjournaled in hang-- erslit extending downwardly into the tank no i fromthe collecting pan. To the shaft is also fixed u. pinion 12 which mesheswith a those carried by the elevator or car.

segmental gear 13mounted on shaft l t, this shaft being journaled at oneend in an upright from the collecting pan 8 and at the other end in abracket 15 fixed as shown to the side of the reservoir. The segmentextends downwardly through a slot in the bottom of the collecting paninto meshing gear with the pinion 12 for actuating the disk 10. Thebracket 15 extends toward the left bey'ond the reservoir and near theend is pivoted the'reto a bell crank 16. One end of this lever carries abuffer or bumper wheel 17, preferably of elastic material such forinstance rubber, and to the other end of the bell crank lever is pivoteda connecting link 18 connecting the lever to a crank arm 19,

fixed to the shaft 1 1; so that by rocking the lever 16 power istransmitted through con necting link 18 and crank arm 19 to the 20 rockshaft 14 which actuates the segmental gear 13 to revolve the disk 10 tosupply oil to the collecting pan. The bell crank lever 16 has therein aslot through which projects a stop 20 fixed to the bracket 15, this stop20 serving to limit the rocking movement of the bell crank lever 16 ineither direction of rocking movement by engaging opposite ends of theslot. may be provided and screwed into the lever 16 so as to projectwithin the opposite ends of said; slot for the purpose of adjusting themaximum rocking movement in either direction. The bell crank lever 16 isalso provided with a cut-out portion 22 into which projects the free endof a spring 9.8,the other end of this being fixed to the bracket 15 inany suitable manner, as by means of a screw. The purpose of this spring23 is to serve as a cushion means for the lever mechanism 4 when themechanism is being actuated, as

shown .in Fig. 1, and also as a retractile means to bring the leveragesystem back to the normal idle position indicated in Fig. 7. All theparts heretofore described are F or actuating the disk 10 through theleverage gearing system above described suitable projections or bumpersare stationed at intervals along the elevator travel in the path of thebumper wheel 17. One of these bumpers 2% is shown in the drawing and iscarried by aportion 25 of the guide rail frame work. As Qhe elevatorpasses this bumper the bumper wheel 17 comes into engagement therewithand the lever 16 is thereby caused to swing in a direction dependingupon the direction of the elevator travel, thereby actuating thetransmission gearing described above to actuate the disk 10 to supplylubri- 0 cant to the collecting pant, thence from the collecting panthrough the conduits 9 to the collecting cone 6 and from there to thevar-i ous distributers.

It is known that side play is always pres- 5 cut in an elevator due toeither defects in Suitable set screws 21,

noeaeas 111g movement being dependent on the relative lateral positionsof the budcr 24 and the bumper wheel. 17 at the time the elevator ispassing. Such variations in rocking move ment would of course result inunequal quantities of lubricant being supplied by the disk 10 to the pan8, as the quantity supplied at each actuation is more or less dependentupon the number of revolutions made by the disk, and in order toeliminate this disadvantageous feature which may be caused by the sideplay of the elevator I propose to mount the bumper 24 yieldingly on theguide rail frame work for lateral movement relative thereto and to makethis latei al movement great enough to take care of the side play of theelevator. In this manner the lever 16 may be given itsmaximum rockingmovement at each actuation of the apparatus regardless of the variationsin the side play. To this end I fix to the portion 25 of the guide railframe a suitable spring 26 preterably of the form shown, this springbeing conveniently secured at its middle point by a set screw 27; andthe bumper :24 is provided in its middle portion with a transverse slotthrough which projects a bolt 28 from the frame work 25 for limiting thelateral movement of the bumper relative to the;

guide rail. This bolt is provided with 'a suit-- able nut and washer forholding the bumper into sliding engagement with the guide-rail frame.The spring 26 as shown presses againbt either end of the bumper 24 toforce it toward the right, the extreme limit, its movement in thisdirection being limited by the bolt 28 coming into engagement with thebumper in the left hand end of the slot.

In the position shown in Fi 1, the elevator is going in the upwarddirection and the bumper wheel 17 is now in the maximum rocking positionfor the upward direction of the elevation The bumper wheel 17 is justbeginning to ,ride off the cam surface of th e'buinper 24, and thespring 23 is in tension to bring the parts back to the normal or idleposition as shown in Fig. 7. If the elevator were going in the oppositedi recti'on the lever 16 would of course be actuatedv in the oppositedirection and the retractile spring 23 would be bearing against theupper surface of the cut-out portion 22 in the bell crank lever 16,tending to bring the parts back to idle position as shown in Fig. 7. Itshould be noted that the spring 26 serves a double purpose: first, asmeans to maintain the bumper in its extreme right hand position toimpart to the lever 16 its nosaess maximum movement regardless ofianyside play of the elevator, and secondly, as cushion means for theapparatus to prevent sudden jars and pounding due to high speed of theelevator and other causes when the bumper wheel 17 strikes the bumperThe transverse slot in the bumper 2% is preferably slightly longer thanthe maximum side play of the elevator in order that there may be amargin of lateral play of the bumper in all lateral positions of theelevator with respect to the guide rail for thespring 9-6 to serve asacushioning ineans all times.

It will be noted by reference to Fig. 1 that a float 29 is provided witha stern protruding upwardly out of the oil tank to in clients the oillevel, thisoil level being shown in dotted lines. This stern passesupwardly through a funnel-shaped member 30 which serves as a means forintroducing lubricant into the tank 1. A cover 32 or any. suitablefornris also illustrated for excluoing dirt, etc, froni'the reservoirand collecting pan. Referring to Figs. 4- and. 5, a guard 31 for the oildisk is shown for guarding against the splashing of oil when the disk 10is driven at a high speed and for directing the lubricant into thecollecting pan 8. This guard 31 may be provided with ears (only onebeing illustrated} cut therefrom. and bent inwardly as shown tofacilitate the collecting of oil from the disk peripheryand directing itdown the incline of the thickened portion 33 of pan 8 into the pan. Theguard 31 carries the wiper 35, the latter being secured thereto by meansof a screw 37. It is tobe noted that the lever arm 16 in the normal oridle position shown in Fig. 7 is in avertical position; that the crankarm 19 may be provided with a plurality 0f pivot points (two beingshown) to which the connecting link 18 may be connected to vary thethrow of the gear segment relative to the throw of the bumper wheel 17;and furthermore the gear segment is symmetrically arranged with respectto the cranl: arm 19 and made. large enough to avoid runningoff thepinion in the maximum rocking movement for which the apparatus isdesigned. The foregoing is illustrative or" only one of the many -Eormswhich my invention is capableof assuming and it is to be understood thatall changes in form that come Within the spirit or my invention are intended to be covered by the claims appended hereto. For instance,inasmuch as the number of lifting disks employed in any particular casedepends upon the demands for lubricant it may be desirable to provide aplurality of disks, as is illustrated in Figs. 8 and 9 where threedi reshown mounted on a, common she," driven by means of a pinion 1E1" jvvith asegment 13, this segment b b mounted in turn on rock shaft it.Each disk supplies l lubricant to a collecting pan 8 and from thence toan individual conduit 9" leading downwardly to an int 'vidual receivingcup 6, each one of these cups leading to a distributor 3 as shown indotted lines.
